I cant read that sorry @Luis_Rivera
OpenStudy (anonymous):
8 y^3 x^2 y^2= 8 x^2 y^5
OpenStudy (anonymous):
How did you even get to this y^3 x^2 y^2
OpenStudy (anonymous):
I want the steps sorry @Luis_Rivera
OpenStudy (anonymous):
Im so confused! Can you explain

Thanks so much @Luis_Rivera for actually explaining it. -___- Medal taken away
Directrix (directrix):
(2y)^3 (xy)^2 = ?
--------------
(2y)^3 means the product of three of whatever is inside the parentheses.
So, (2y)^3 means --> 2y * 2y * 2y = 2 * y * 2 * y * 2 * y
Directrix (directrix):
2 * y * 2 * y * 2 * y is the same as 2*2*2 * y * y * y which is 8 times y to the third power.
8 y ^ 3 --->
Now for the other factor.
Directrix (directrix):
(xy)^2 means (xy) times (xy).
So, (xy)^2 = x * y * x * y = x * x* *y * y.
Simplified, that product is x^2 * y^2 or x^2 y^2
Directrix (directrix):
So far,
(2y)^3 (xy)^2 = 8 y ^ 3 * x^2* y^2
